The Customer undertakes to pay Opinum a fee in exchange for the provision of Services by Opinum. The amount of the fees is included on the Opinum website.

The prices are stated in euros and exclusive of tax; therefore, prices will be increased by the taxes applicable on the day of the billing.

Opinum shall issue a monthly invoice for the basic version of the Services and a monthly, quarterly or annual invoice depending on the amount of data created or downloaded in the Portal.

Payment must be made to the bank account of Opinum (A/c no. BE53 0017 6938 2353 at BNP Paribas Fortis no later than 30 days from the date of billing. The Customer is solely responsible for the payment of any bank charges.

The fee may be modified at any time by Opinum. However, such a modification will not apply to the current month or the following month in order to allow the Customer time to terminate the Contract under the conditions provided for by these terms and conditions if they do not accept the new tariff.

Accordingly, the Customer is invited to regularly consult the tariffs in force on the site

In the case of non-payment, even partial, of an invoice, whatever it is, by its due date, Opinum reserves the right to suspend the Services until receipt of full payment of the sums due.

The suspension of Services, in the case of non-payment, does not give the right to a refund or any compensation in favour of the Customer. In the event of default of payment by the Customer, Opinum shall retain the data for 3 months. After this period, the data shall be destroyed.

Expenses relating to non-payments are charged to the Customer. Any delay in payment will lead to, as of right and without prior notice, the charging of interest at a rate of 15% per year on all amounts still owed on the date. This interest is due by the mere fact of the failure to pay be the due date and is without prejudice to the option to terminate the Contract.

Any invoice totally or partially unpaid by the due date shall also be increased, as of right and without notice, by a lump sum of €125 or of 15% of the amount outstanding, whichever is greater.

The costs for the reminder of unpaid debts shall be charged to the Customer up to a maximum of €10 per registered mail.

This guarantee does not apply in cases of:

  • defects or damages resulting from the third-party components that were not provided by Opinum.
  • Insufficient Internet connection provided by a third party for the use or the provision of the Services.

In the event of a breach of the guarantee, the amount of damages which may be charged to Opinum may not exceed, all damages combined, the amount of the fee charged for the month during which the Services have been affected.

Opinum is under an obligation of means taking particular account of the risks inherent in the technologies used.

The Customer is solely responsible for the establishment of internal security requirements to avoid a third person accessing its accounts.

The Parties undertake to keep information relating to the Services confidential throughout the duration of the Contract and for ten (10) years from the termination of the contractual relationship for any reason whatsoever.

Confidential information is all the information communicated by Opinum to the Customer, regardless of the means of communication used, oral or otherwise (hereinafter, "Confidential Information"), to the exclusion of information that the Parties expressly identify as being non-confidential at the time of its communication.

This list is purely illustrative.

The Parties undertake to return, on simple request of the other party, any document relating to confidential information.

Information is not confidential if the party can prove that this information:

  • is in the public domain, namely that this information has been publicly disclosed, in particular by the general or specialised press, prior to its communication, or has been made public, subsequent to its communication, otherwise than by breach of this clause;
  • was known to the receiving party prior to its communication by the disclosing party.



The information communicated by the Customer shall be included in an Opinum file.

The data communicated by the Customer are exclusively professional and cannot be considered personal data within the meaning of the European General Data Protection Regulation (EU Regulation 2016/679 of 27 April 2016). If, however, personal data were to be communicated by the Customer, Opinum undertakes not to use them for profiling or commercial purposes.

Please also refer to our privacy policy


Any notification which must be made from one of the undersigned parties to the other, must be made by registered letter with acknowledgment of receipt. These notifications shall take effect on the first working day following their mailing.

In the case where an article of this Contract is declared null and void by a competent jurisdiction, such invalidity shall not affect the other provisions or articles which shall remain valid.

The Parties shall make every effort to replace the cancelled provision by a similar provision expunged of its cause of nullity.

Any change, modification or extension of this Contract must occur by common agreement.

The Contract includes the entirety of the obligations of the Parties with regard to its subject matter. It cancels and replaces all previous agreements between the Parties, whether oral or written, having the same subject matter, including the general terms and conditions of the Customer.

Only a written addendum duly signed by the Parties may validly amend the provisions of the Contract. Except as expressly provided for in the Contract, no change can be the result of an exchange, even written, between the Parties, or be inferred from the conduct or the comments of a Party, without the signing of such an addendum.

Each Party acts in its own name and on its own behalf in the capacity of an independent contractor. Neither Party has the power nor the authority to bind the other Party in any way. None of the provisions of the Contract may be construed as creating, between the Parties, a mandate, subsidiary, relationship of agent or employment relationship.

The fact that one of the Parties has not required the application of a provision of the Contract may in no way be considered as a waiver of the rights held by that Party under said provision.



All disputes arising between Opinum and a Customer are of the exclusive jurisdiction of the courts of the judicial district of Hainaut.



Belgian law applies to these general terms and conditions.
